KIDS TRIVIA

Detailed explanation-1: -The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.

Detailed explanation-2: -As rain gauges measure the volume or weight of precipitation collected in a vessel with a fixed orifice diameter, the size of the orifice needs to be standardized. CIMO provides that its area should be 200 cm2 or more, and types with an orifice area of 200 to 500 cm2 are widely used.

Detailed explanation-3: -A rain gauge basically collects water falling on it and records the change over time in the rainfall depth, which is usually expressed in mm.

Detailed explanation-4: -Meteorologists measure the rainfall using an instrument known as a rain gauge. It is also called as Udometer or Pulviometer or Ombrometer. They can measure the exact amount of rainfall. Rainfall is expressed in centimetres or millimetres.

Detailed explanation-5: -Rain gauge is an instrument for measuring the amount of rainfall.
